TO ALL WI-IOM IT MAY OONCERN:

Be it known that I, SIMON CONRAD, of Petaluma, in the county of Sonoma, and State of California, haveY invented a new and useful Improvement in Attachmcntsof Cultivators and Harrows to their Trucks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, in which- I Figure 1 is a side elevation, and

Figure 2 a plan or top view.

Figure 3 is a plan of the cultivator.

The nature of my invention consists in so constructing `the truck or carriage and the harrow and cultivatorthat they can be attached alternately at pleasure, so as to avoid the necessity of making a truck or carriage for.each,'and thus save the expense of an extra truck, which is au important item.

In-the drawings, A are the wheels, B the axle, the` tongue, D D the braces from the tongue to the axle. Upon this tongue, the axle and braces, I 'erect a seat forthe driver, as shown in iig. 1, E E E E' E being posts attached at their lower ,ends to the braces' D and axle B, as seen ini-ig. 2. Three of them are seen also in iig. 1. On the upper ends of said posts I place the seat F. The two pieces Gr Gr, g. 2, one of which is seen at Gr, iig. 1, areattached at their low-er ends to the posts E E,.near the axle B, and at or near their centre they are attached to the posts E E', as seen at a in iigs. 1 and 2, and ou their upper forward ends are placed two cross-pieces H H, which form a rest for the fc'et of the driver.

' Into the axle B, as shown at c c c c in'ig. 2, and at @,ig. 1,.I secure foureye-bolts,throughall of which the long bolt X extends. Upon this long b'olt, and between each pairof the eye-bolts, are placed the pieces b b, having the brace al attached to them to keep them parallel with each other. Through the eyes at the posterior ends of these pieces b b is a long bolt, e. On thev ends of this bolt, outside the piecesb In,l are placed the lower I -ends ofthe forked upright bar f, the upper'end of which is formed with a long mortise or slot, through which the lever I passes, and having a series of holes through it for the purpose of graduating the altitude of the lever I, by means of a suitable pin through theI said holes and through the lever I. Just outside of the ends of this forked barf, :indou the same bolt e, are placed the braces or supporting-bars g g, the lower ends of which are attached to the harrow K by means of eye-bolts, as seen at t L.

To theextreme posterior end of the lever I are attached the brace or supporting-rods it', which are attached at their lower ends to the harrow by means of the eye-bolts, as seen atjj. The lever I ypasses the part E, and works on a fulcrum-pin inserted in the part, as seen at 7c, iig. 1; and the lever I is provided with a series of holes for the purpose of changing its position fore and aft upon the fulcrum-pin 7c, as may be desired.

To the forward end of this lever I, at Z, is attached a bar, m, which extends downward to and past the'lever 22. The lower end of this bar m is made with a long mortise or slot, through which the forward e'nd of the lever n passes, both being provided with a series of holes, by means of which and their pin the lever can be regulated Aat pleasure. This lever 'ftis'rigidly attached, at its posterior end, to the oscillating-shaft o, which works in bearingsp p on the tongue C and post E, just in front of the axlc B. On the opposite enoyof the shaft o is a rigid drm, 1', with a stud extending therefrom, as seen at s, To this arm 1' is attached the long lever t, by means of a bolt, y, at the extreme lower end lof the lever t; and the stud s, at the end of the arm r, passes through the lever t, as seen at s, and the lever t works freely thereon,

I attach to the brace D, at 2, and to the post E,.at 3,.,g. 1, the segment L, the outer edge of which is notched to receive the leaf tt of the 'lever t, so as to hold it in the desired position. I attach the lever M, at its lower end, to a bar or rest, N, by a small bolt or pin, o, this bar N being firmly attached to the brace D in any convenient why. This lever M passes upward and `backward past the post E, and through aguard, w, which is firmly attached to the said post. This guard is provided with a notch on the upper side of its horizontal part, which extends from the said part at z, and which cannot be seen in the drawing. Into this notch the lever AM isyplaced, and when there i't bears against the outside of the lever t, holding its projecting leaf 'it in the notches of the segment L.

I construct my harro'w in'a'ny` known and desired way, and attach the eye-bolts h and j to the same, to correspond with the construction of the attachment-devices, as described. 4

I make my cultivator as follows, viz: I construct u frame, A A, iig. 3, of' any desired length, say from four to six feet, the timbers being about three by five inches square; and at the forward end of this frame, and'on the outside of each piece A, I secure a bar of iron, a, which extends a few inches forward ofv the pieces A A; and through these bars a a, in -front of said pieces, are holes of thel proper size to receive the long bolt, c', of figs. 1 and 2, when it is desired-to attach the cultivator to the truck or carriage.A In th'e posterior crosspiece of this frame A is placed an eye-bolt, b, towhich is attached the bar c, which has a long mortise or slot iits upper end, as seen at CZ.' Through this piece is a series of holes extending nearly the whole length of the said mortise el to receive a pin, whichl attaches it to the after end of the lever I in figs. 1 and 2, so that it can bcY regulated, as to' elevation, as may be desired. To thc under side of this frame A, I secure two pieces, B B, by' means of screwbolts, or in any suitable way, and at any desired angle. These pieces may be of any convenient length, say from iive to'eight feet, and about three by ve inches square; and tothe under sides of these pieces I attach a series of cultivatorteeth, each tooth being attached by'means of two bars of'iron, which are welded together at their lower ends, and then-diverge-in such a manner as to allow their upper ends to be attached to 4their respective pieces. B B, oneto each, 'thus forming a figure resembling the letter V, to the lower part of which, at the point or place of union of the two barsI secure, by means ofbolts, the cultivator-teeth. All this may be done as may bestsuit the desire of the builder.

When I desire to remove the harrow and use the eult'ivator, I take out the long bolt e, ligs. 1 and 2, and remove the braces or supporting-rods g g, and remove the long braces or supporting-rods t' Ifrom the end of the lever I; then remove the barrow; and I thenplace the eyes of the piecesa a, which are attached to the frame of the eultivator, on the outsidesof the pieces b b, figs. 1 and 2, and in such a-manner as that the bolt e, figs.

1 and 2, will pass through'them all, taking care to see that said bolt also passes through the eyes ofthe forked y supporting-mdf, as itiisused "with both harrow and cultivator. I then place the supporting1od c, fig. 3,of the cultivator upon the end of thejlever I, figs. 1 and 2, `by passing the end of the lever into the imortis'e d of the rod c, andsecu'riugthern, `as desir`dby means of a pin or bolt7 in any one Vot' the series of holes in the same, and thusithe connection ismadefand the cult-ivatorv ready for u'sc.

When fitis desired vtcp elevate the"harrowor lcultivator, whew-using them, it is done by lifting thelever M Vout of thenoteh in the guarclmiigsfland2,and21noving it outwards from the lever t, andthen pressing the latter down, which operates the V'oscillatiiig-shaft fo 'audits lever n, and by means of the rod m; this motion is made to draw the forward end of the'lever I down, and of course the after end is correspondingly elevated, and

with it the supporting-rods, which areattached'to said lever, and also to the barrow or cultivator, are raised, I

and with them the cultivator or'harrow is raised, and by holdingth'e lover t in any desired notch in the segment' L, their altitude is regulated as may be needed; v

When a gang of ploughs are used with the truck or carriage, the spindles, on which the truck-wheels are placed, are se attached tothe axle B as to bring the inner ends of the hubs of said wheels close up to the ends of theaxle,and the spindle of the wheel which travels in thefurro'wis attached tothe under side of the said axle,` and the one upon which the wheel is plaeed, that travels on the land, is attached-tothe upper side of said axle, in order to compensate for the di'erent height'of the furrow and land,lso asto, secure, as near as may be, a horizontal position for the axle B, but when the cultivator or harrow is' used, the said spindles are both attached to the under side of the axle, and as there must be more space betweeu"thewhcels ofthe truck, when the cultivater or harrow is used, than when the, gang-ploughs are attached,` Imalie,` the spindles P,iliig. 4, from eight inches to a foot longer inwards than is necessary for the plough-attachment, so that, when the ploughis attached, they extend inwards from the screw-bolts Q to the holes R, iig. 4, so'that, when desire to remove the plough and attach the barrow or cultivator, I unscrew thefclasp's Sand bolts Q, fig.'4, and move outward the spindle I), so that the bolts Q willl pass through the holes in thespindles, nearest their ends,land then tighten up both the bolts and clasps, and thus Athe spindles are extended outwardsvon each endroffthe ankle, to the extent of the distance between the two holes in the spindles, and thus more room is obtained betweenthe wheels for the harrow and cultivator, which is very necessary. i i p Having fully described my invention, what I claim, and desire Vto-secure by Letters Patent, is.-

1. The connecting-devices, by which I attach, at pleasure, the cultivator or the barrow alternately to the truck or carriage, all as shown and described. Y i

2.' In combination with theiabove, the construction of the spindles on which the wheels of the truck are placed, so that they may be so placed on the axle as to increasev or decreasethe distance between the wheels, as may be desired, all as and for the purposes shown and described. l
